I had always thought that the Reichstag election of March 5, 1933 held a month and a week after Hitler had been appointed chancellor were the last multi-party elections held in Germany until after the war, and of course they were held in less than democratic conditions, with many leftists under arrest or fearing arrest, newspapers being banned etc.
However, according to a biography of Goebbels that I'm reading, there were local elections held throughout Prussia on March 12, 1933. According to this, the NSDAP won 38% of the Berlin vote, an improvement from the 34.6% the party won the week before.
Does anyone have any information about this. Haven't found anything on the internet, and the source in the biography was the Berlin statistische Jahrbuch 1933.
Results for Prussian provincial assemblies ("Provinziallandtage") including the provincial-level city of Berlin can be found at gonschior.de/weimar/Preussen/Provinzen.html (sorry, no links yet). As to lower-level results...you can find a lot of them online, but not collected centrally on any particular site.
The change in Berlin from March 5 to March 12 is mostly explained by lower turnout (76% versus 87%) and a lower KPD result (19% versus 24%), i.e. KPD voters abstaining.
